Lifting ceiling for underground mine mining excavator
The invention discloses a lifting ceiling for an underground mine mining excavator. The ceiling comprises bases, first supporting pipes, second supporting pipes and a top plate, wherein the top platecomprises a protective plate and a supporting plate, mounting grooves are formed in the center of the lower surface of the protective plate; telescopic springs are uniformly and fixedly mounted at thetops of the inner walls of the mounting grooves through bolts; and the supporting plate is fixedly mounted at the ends, away from the tops of the inner walls of the mounting grooves, of the telescopic springs through bolts. Through adjusting the lengths of the second supporting pipes inserted into the first supporting pipes, the height of the top plate can be adjusted, so that the height of the top plate can be adjusted according to the space height of an underground mine, the excavator can conveniently move in the underground mine, an excavator cab can be protected through the top plate, theexcavator can conveniently move by adjusting the height of the top plate, and the working efficiency of the excavator is improved.
本发明公开了一种地下矿开采挖掘机用升降式顶棚，包括底座、第一支撑管、第二支撑管和顶板，所述顶板包括防护板和支撑板，所述防护板下表面的中心处开设有安装凹槽，所述安装凹槽内壁的顶部通过螺栓均匀固定安装有伸缩弹簧，所述伸缩弹簧远离所述安装凹槽内壁顶部的一端通过螺栓固定安装有支撑板，本发明通过调节第二支撑管插入第一支撑管内部的长度，能够调节顶板的高度，这样能够根据地下矿的空间高度，调节顶板的高度，方便了挖掘机在地下矿内移动，这样不仅能够通过顶板对挖掘机驾驶室进行保护，而且通过调节顶板的高度，也方便了挖掘机的移动，提高了挖掘机的工作效率。
